Very-last-minute Galaxy S4 Event Speculation - Vine exclusive?

I just had a last-minute thought. Do you think Samsung will reveal Vine as a timed-exclusive to the S4 during the event today?

It seems odd that we've heard nothing about the Android Vine port since the app was originally released for iOS. Considering the S3 came with a timed-exclusive of Flipboard for Android, could we be looking at the same thing for Vine? Could the camera app itself even have some sort of Vine-integration, similar to HTC's ZOE?
